Bruno Senna Lalli (born October 15, 1983 in São Paulo) is a Brazilian racecar driver and the nephew of late three-time Formula One world champion Ayrton Senna. His mother is Ayrton's sister, Viviane. His father died in a motorcycle crash in 1995.

When leaving McLaren at the end of 1993, Ayrton Senna had said: "If you think I'm good, just wait until you see my nephew Bruno". Bruno raced go-karts against Ayrton on the family farm, and it was clear that Ayrton regarded his nephew's potential very highly. Ayrton's tragic death while driving a Williams at the 1994 San Marino Grand Prix, however, brought Bruno's own racing career to an abrupt halt.
